Description
Recombinant Human T-cell-specific surface glycoprotein CD28 is produced by our Mammalian expression system and the target gene encoding Asn19-Pro152 is expressed with a Fc tag at the C-terminus.
Alias
CD28; CD28 antigen; CD28 molecule; T-cell-specific surface glycoprotein CD28; Tp44; TP44
Endotoxin Testing
Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Purity
Greater than 95% as determined by reducing SDS-PAGE.
Formulation
